Since it is a product of Asahi, it is solid and can be used with confidence, even lower-priced items are sold but there is anxiety in the shape of the body, but I tried it once again but asahi I returned to the valve.

It was heavy and inconvenient with conventional metal to attach this machine to the handling tool and work, but it became lighter by the machine and work became easier. However, there are places that are vulnerable to scratches and shocks, requiring periodic replacement. For this reason I also want to make the price cheaper.
